Description:

This diagnostic trouble code, TSC 000597.19, is triggered when the BCU (Brake Control Unit) transmits incorrect sensor status signals on the CAN BUS. These signals indicate either:

• The brake pedal sensor is not available.
• The sensor signal is faulty, possibly due to a circuit problem at the brake pedal sensor unit.

Reaction:

When this error is detected, it may result in unreliable brake pedal signal transmission, potentially compromising braking performance and safety.

Recommendations:

Inspect Brake Pedal Sensor:

• Check Sensor Availability:
  • Ensure the brake pedal sensor is properly installed and configured in the system settings.
  • Reconfigure if necessary.

Inspect Sensor Circuit:

• Check for Circuit Issues:
  • Inspect wiring and connections of the brake pedal sensor for any signs of damage, loose connections, or corrosion.
  • Repair or replace any faulty components.

Validate CAN BUS Communication:

• Check CAN BUS Data Integrity:
  • Ensure that CAN BUS communications are functioning correctly and no erroneous messages are being transmitted.
  • Repair or replace any faulty CAN BUS components.

Note:

Regular maintenance of the brake pedal sensor and CAN BUS system is essential to ensure reliable braking performance. Address any issues promptly to maintain safe operation.
